I have a necklace that appears to be made of stainless steel, although for the size of the crystal rhinestones on it, it should be heavier, so maybe the metal is aluminum. The clasp is heart-shaped and seems a little modern (maybe '90's). At the end of the extender chain, there is a tiny little metal tag with a rhinestone. The tag is embossed with a symbol that looks like two letter 'J' facing each other over a circle, that's the logo I can't seem to find anything about. Thanks in advance for any ideas....
